hi, may i know for this stm32vldiscovery, whether i could use PA1 and PA2  or PA9 and PA10 for uart communication? because i checked the schematic and datasheet, still not very sure.

Fort UART1 PA9/PA10, for UART2 you can use PA1/PA2.

Run STM32CubeMX and try to enable UARTx port to se what port are used. Of course they are alternative pin assignments possible - in some case. The CubeMX is really good at it if do not use datasheet...
